| 摘 要： | 以废旧聚乙烯和聚丙烯塑料及中石渣作为原料，采用模压成型工艺与挤出成型工艺制造复合模板。对2种成型工艺所得模板样品的宏观形貌与力学性能进行了比较。结果表明，挤出成型工艺更适合复合模板的成型加工，挤出成型工艺生产的模板宏观形貌致密、均匀，冲击强度、弯曲强度、弹性模量比模压成型工艺所得模板分别捍高了29. 8%,36. 6%,25. 9%。

| Abstract: | Compound formworks were made from waste plastics(PE,PP) and carbide slag,and two molding methods,hotpressing and extrusion were compared.It showed that the extrusion molding was superior to hotpressing,dense and even-texture,better mechanical properties were obtained.The impact strength,the flexural strength,and the elasticity modulus of the extrusion based formworks were 29.8 %,36.6 %,and 25.9 % higher than those based on hotpressing molding. |
